the solution is soo dumb.. i was stuck at this challenge for 3 days.. thought of some complex stuff.. in 10 point challenge.. but no.. the answer is simple and very very dumb.. anyone wanting hints... well.. no hints do it yourself.. its very easy

btw.. nice challenge.. researched and learnt a lot.. Thankyou..

hint please

Good challenge. For beginners: Whenever you are given executable, you must take a close look at it with proper tools...

I'm really stuck here tho, can u pls provide more hint about proper tool? I used wine but couldn't run it

There is another tool mentioned below, also you should definitely have IDA in your toolkit.

Would be very interesting to look for this in real apps in the future.

Great :)

Good one!

nice one!!

I have no idea

Try to find vulnerability in that app

Oh boy, I solved the challenge now. I saw the vulnerability from the start, but didn't know that syntax existed. Honestly, ChatGPT helped a lot. It gave an example of the attack, and that's exactly it.

I still cannot open that app by wine, can u pls provide more hints?

Use a decompiler like Ghidra to just see the source code.
